الْحَجُّ وَاجِبٌ عَلَى الْأَحْرَارِ، الْمُسْلِمِينَ، الْبَالِغِينَ، الْعُقَلَاءِ، الْأَصِحَّاءِ
Translation: Hajj is obligatory upon free, Muslim, adult, sane and physically fit persons.
The five descriptors are free status, Islam, adulthood, sound mind and bodily capability. They include historical social categories and conditions of legal responsibility and ability.
Here “wājib” conveys the binding obligation of Hajj established by the Qur’an; it does not demote Hajj to a lesser duty.
